4 new car fuels worth knowing

With constant pressure on the earth’s resources, consumers are constantly looking for alternative fuels in a bid to reduce their carbon footprint and play their part to help save the planet.


Air powered cars could be the drive of the future

It’s the perfect solution and it’s one that motorists dream of, and that’s to have their car running on compressed air. It works by propelling the release and expansion of the gas within a pneumatic motor. This air, which has a low energy density, can replace petrol in a combustion engine to work the pistons which in turn produces the power required to drive the vehicle. There are also no tailpipe emissions which makes it a favourite with drivers who aspire to reduce their carbon footprint. Some car makers have even suggested that air-powered cars could be factored in to their mainstream vehicle production.

Heat is another energy source that vehicles could benefit from. At least two-thirds of the energy in gas used in cars and other vehicles is wasted as heat. This wasted heat can be captured and turned into energy, reducing the fuel requirements of the vehicle and improving the miles per gallon. However, the high cost of thermoelectric materials has prevented this from becoming a reality in vehicles.


An obvious solution is hydrogen

For many drivers, the obvious solution instead of petrol and diesel is hydrogen. It’s one of the most abundant substances and the by-product of burning hydrogen is increased water which avoids any sort of pollution. However, it is expensive because it’s normally bonded to another substance, like oxygen. Separating and cooling it is also expensive.

These are all possibilities for the future. Motor dealers might not have any of these cars on their forecourts just yet but they still need motor trade insurance for their standard stock.
Companies offering motor trade insurance can be found via an internet search.

According to Top Gear the lifetime CO2 emissions from an electric car are half what they are from a conventional vehicle.

Liquid nitrogen was first experimented with back in the 1900s to power cars. However, it is not an energy source on its own, and electricity or some sort of fossil fuel is required to pressurise the air to create the liquid nitrogen. Then the energy is released and the car becomes operational.
